Abstract
A multiport frame exchange system is disclosed having a plurality of input and output lines and which outputs frame data inputted from these input and output lines to desired input and output lines based on frame header information. This multiport frame exchange system is composed of input frame buffers provided for each input line that store inputted frames; output frame buffers provided for each output line that store and output output frames; a header processor that processes the headers of frames; and a self-routing section that connects the input frame buffers, the output frame buffers, and the header processor.
